The device provides a rich set of Enterprise Ethernet switching features.

Using multistage Versatile TCAM technology (VCAP™), it delivers VLAN

and QoS processing that enables delivery of differentiated services,

security through intelligent frame processing, and egress frame

manipulation.

For industrial applications, VSC7448 integrates VeriTime™, Microsemi’s

patent-pending distributed timing technology that delivers the industry’s

most accurate IEEE 1588v2 timing implementation.

A powerful 500 MHz CPU enables full management of a Layer 2 and

Layer 3 Ethernet switch solution.

• Integrated 500 MHz MIPS 24KEc CPU with MMU and DDR3/

DDR3L SDRAM controller

• PCIe 1.x CPU interface

• Internal shared memory buffer (8 queues per port)

• Jumbo frame support

• Strict priority and DWRR scheduler/shaper

Layer 2 Switching and Layer 3 Forwarding

• 802.1Q VLAN switch with 32K MACs and 4K VLANs

• Push/pop/translate up to three VLAN tags on ingress and

egress
